MACHINE FOR MAKING TUBES FROM FIBROUS MATERIALS.

To all whom it may concern Be it known that I, CLARENCE THORVALD I'IANSEN, a citizen of the United States, residing at Lancaster, Lancashire, England, have invented new and useful Improvements in Machines for Making Tubes from Fibrous Materials, of which the following is a specification.

This invention relates to machines for making cylinders, tubes and like articles, such as roving cans, by winding a web of fibrous material on a preferably collapsible mandrel and simultaneously compressing and consolidating the several layers of material on said mandrel by means of a calender roll.

According to the present invention, in order to facilitate the removal of the cylinder or tube from the mandrel after the winding operation is complete, means are provided for moving aside the hearing at one end of the mandrel and at the same time lifting the calender roll from the mandrel, which is supported, driven and operated from the other end. For this purpose, the said movable bearing consists of a bearingbox divided into two along a vertical plane extending through the axis of the journal or trunnion, each half of said box being supported on a substantially vertical arm or lever. These arms or levers are pivotally supported at their lower ends and are connected together by gearing such that when one lever is moved laterally away from the journal or trunnion, the other also moves laterally away from said journal or trunnion in the opposite direction. To open and close the bearing-box, one of the said arms or levers in connected by suitable gearing, such as a link and a crank, to a shaft provided with a crank-handle or hand-wheel, so that by turning said crank or wheel the halves of the bearing-box can be moved toward or away from each other. The said wheel is also rovided with a notch or recess, in which a 0g or pawl is adapted to engage when the bearing-box is closed. Any other suitable locking device can however be employed for this purpose.

In order to effect the lifting of the calender-roll from the mandrel simultaneously Specification of Letters Patent.

with the opening of the bearing-box, the crank-shaft above mentioned has fixed thereto a cam which acts on a lever-arm on a shaft towhich are fixed two other leverarms carrying the bearings of said calender-roll. By suitably setting this cam, the lever arms can be oscillated to raise the calender-roll and maintain it in its raised position at any required time relatively to the opening of the bearing-box. By these means, the cylinder or tube, after the winding on is completed, can be very readily removed by drawing it off the end of the mandrel between the separated halves of the bearin -box.

In tie accompanying drawings :-Figure 1 is a side elevation of the improved cylinderor tube-making machine, and Fig. 2 a front elevation thereof.

a is a tank forming the base of the machine and having standards 6, b; 0 is a rolled up band or web of paper, which is guided by means of rollers (Z, (Z so as to pass through the liquid in the tank a, from whence it passes over the calender-roll e on to the mandrel 7, being meanwhile pressed between said mandrel and the calender-roll as shown.

The mandrel-shaft g is supported at one end in bearings it, h and is here shown as driven through spur-gcaring j, 70 from a coun tershaft m provided with a stepped driving ulley 'n. The mandrel f is preferably c01- apsible and adapted to be distended and contracted for-example as in application Serial No. 592,531 by means of a screw-threaded spindle 0 which can be rotated in either direction by means of a pulley p having a loose pulley q, g on each side for ano en and aerossed driving belt. The other en of the mandrelshaft 9 is supported, during the winding-on of the paper band 0, by means of a bearingbox divided along a vertical plane into two parts If, t respectively mounted on the upper ends of arms or levers u, a, which are pivoted at v to the outside of the tank a. Each of these arms a, u is connected by a link '10 to one of two diametrically-opposite crankpins 00, a: on a disk 3 which is pivotally mounted at a on the base a. The arm a is moreover connected by a link 1 to the pin 2 of a crank-disk 8 mounted on a shaft 4:, which is rotatably mounted in suitable bearings in the standards I), b. The shaft at also has fixed thereon a hand-wheel 5 provided with a notch or recess 6 in which engages a pivoted do-g or pawl 7, whereby the arms a, a together with the bearing-box sections t, t can be retained in the positions shown in Fig. 1. which, when the said shaft is turned to separate the bearing-box-sections t, 25, act on the lower end of arms 9, 9 fixed to a shaft 10 rotatably mounted in vertically adjustable bearings 11 in the standards I), b. This shaft 10 has fixed thereto arms 12, 12, on which are mounted the bearings 13, 13 of the calender-roll e. The bearings 11, 11 are supported on screw threaded adjusting shafts 14L, l t whereby the height to which the calender roll is raised by the cams 8, 8 can be varied within limits.

The operation of the improved mechanism is as follows :-.If it be desired to remove a cylinder or tube from the mandrel f, the mandrel is collapsed e. g. by means of the spindle 0, and the dog 7 removed from the notch 6 in the wheel 5 which is then turned clockwise (Fig. 1) so as to draw outward the arm a by means of the link 1. This motion of the arm a by means of the link to causes the crank-disk z to rotate and to force outward the arm a by means of the link w. This motion is continued until the bearingbox-sections t, t are sufliciently far apart to permit the drawing off of the cylinder or tube from the end of the mandrel 7. During this motion, moreover, the calender-roll e is raised by the action of the cams 8, 8 on the levers 9, 9, so as to release the said cylinder or tube on the mandrel 7. Other suitable gearing may be employed for enabling the arm a to be moved outward by the movement of the arm a in the opposite direction, for example, the said arms can be mounted on separate pivot-shafts and be connected by segmental gear-wheels.
